Method and system for detecting adverse road conditions using radar

Example embodiments relate to techniques for detecting adverse road conditions using radar. A computing device may generate a first radar representation representing a field of view of a radar unit coupled to a vehicle during a clear weather condition and store the first radar representation in a memory. The computing device may receive radar data from the radar unit during navigation of the vehicle on the roadway and determine a second radar representation based on the radar data. The computing device may also perform a comparison between the first radar representation and the second radar representation and determine a road condition of the road based on the comparison. The road condition may represent the amount of precipitation located on the road and provide control instructions to the vehicle based on the road condition of the road. 示例实施例涉及用于使用雷达检测不利道路状况的技术。计算设备可以生成表示在晴朗天气状况期间耦合到载具的雷达单元的视场的第一雷达表示，并将第一雷达表示存储在存储器中。计算设备可以在载具在道路上导航期间接收来自雷达单元的雷达数据并且基于雷达数据确定第二雷达表示。计算设备还可以执行第一雷达表示和第二雷达表示之间的比较，并基于比较来确定道路的道路状况。道
